| mozmck | I made a custom kernel based on the ubuntu sources. In my /lib/modules/2.6.31-15-generic/ there is an initrd directory with vesafb.ko in it, but in my custom kernel's modules directory there is no initrd directory. Why is this? What do I need to do to get that? I built my package with make-kpkg. | 03:06 |
|---|---|---|
| mozmck | anyone here? | 03:35 |
| dandel | mozmck, yes. | 03:53 |
| dandel | I'm doing a little bit of extra testing to see if bug 484943 is only valid on a wubi based install. (currently installing on a native hd partition) | 03:55 |

| _ruben | could anyone enlighten me on how to add a custom built kernel (ubuntu git method) to our custom package mirror (which uses mini-dinstall)? | 07:57 |
| _ruben | the debian/rules binary-<flavour> only creates .deb files, no .dsc and/or .changes | 07:57 |
| AceLan | _ruben: debuild -S -sa -i -I | 07:58 |
| _ruben | AceLan: i doubt that that'd make my binary .debs "dput-able" ? | 08:01 |
| AceLan | _ruben: yes, it will produce necessary files dput needs | 08:05 |
| AceLan | including .dsc and .changes | 08:05 |
| _ruben | the changes files only references the source, not the binaries i had already built | 08:13 |
| cankoy_ | Does the swap part. have to be *at least* the same size as RAM for hibernation to work? | 10:50 |
| cankoy_ | I vaguely remember that Ubuntu kernel does some compression, hence swap d | 10:51 |
| cankoy_ | ...could be less | 10:51 |
| hyperair | depends. | 10:53 |
| hyperair | there are three approaches for hibernation. | 10:53 |
| hyperair | swsusp, uswsusp, and tuxonice | 10:53 |
| hyperair | ubuntu uses swsusp by default. | 10:54 |
| hyperair | uswsusp compresses the image, and so does tuxonice | 10:54 |
| hyperair | but imo tuxonice does it best | 10:54 |
| hyperair | swsusp is extremely slow, and uswsusp is slightly less slow, but that's a different matter. | 10:54 |
| hyperair | cankoy_: ^ | 10:54 |
| cankoy_ | hyperair: so the default scheme does not compress? | 10:55 |
| hyperair | it does not | 10:55 |
| cankoy_ | hm, ok | 10:55 |
| hyperair | it also does not save/restore the file cache upon resuming | 10:55 |
| hyperair | and also only restores half of the memory after resuming, resulting in a whole load of page faults upon resuming. so even if your resume didn't take that long, it'll hang and page fault for another 3-4 minutes before you can use it again | 10:56 |
| hyperair | iow, for now, hibernation sucks and you're better off not using it >_> | 10:56 |
| cankoy_ | ok, thanks for insight, much appreciated ;-) | 10:57 |
| hyperair | np | 10:57 |

| JohnT | Hi! My problem: I have an app with 4 threads wich should run at 100% on each core. I have a 4 core processor. The behavior is not obvious: 2 threads runs on their own core at 100%, while the other 2 shares one single core, leaving the other core idle. Why? | 16:16 |
| mozmck | you don't have isolcpus set in the boot line do you? (disclaimer - I know almost nothing!) | 16:18 |
| JohnT | no, just googled isolcpus: didn't even know it :) | 16:20 |
| nick_schembri | hello, Can someone comment on aufs in 10.4 lucid | 16:30 |
| nick_schembri | cj you work on the cdrom build? | 16:36 |
| mozmck | how do I get my custom kernel's initrd to load the vesafb module by default? the kernel is built with the ubuntu sources and config from 2.6.31-15-generic. I found something on adding it to /etc/initramfs-tools/modules/ but will that work for installing the debs on another computer? | 16:41 |
| cj | nick_schembri: nope. that was kinda' random... | 16:44 |
| cankoy | mozmck: kernel .deb includes the initrd. But I'm not sure just adding vesafb to initramfs-tools/modules is enough to make it work. | 16:53 |
| nick_schembri | cj yes that is a little random. I had your nic in my head. I know that the person who is working on the cdrom build will know if aufs is going to be removed from lucid 10.4. | 16:53 |
| mozmck | cankoy: I installed on a computer with intel onboard gpu and it wouldn't boot. So I booted with ubuntu kernel and added vesafb and fbcon to initramfs-tools/modules, ran update-initramfs -c -k and now it boots fine. | 16:58 |
| mozmck | my custom kernel boots now that is. | 16:59 |
| mozmck | so how do I make it use those modules in the initrd created when I build debs? (I used make-kpkg) | 17:00 |
| cankoy | mozmck: IIRC, you cannot use vesafb on intel gpu because it conflicts with KMS (and inteldrmfb) | 17:01 |
| dandel | i tested bug 484943 on native ext3 suspend, and it crashed just like what it did with a wubi based install. | 17:01 |
| ubot3 | Malone bug 484943 in linux "resume crashes with ext3 error with wubi based install" [Undecided,New] https://launchpad.net/bugs/484943 | 17:01 |
| mozmck | cankoy: I had to use nomodeset on this one to get it to boot reliably and to find the correct resolution. | 17:02 |
| mozmck | in x that is. with the standard kernel it worked but mine had to have the vesafb module - I guess to fall back on. | 17:04 |
| mozmck | the Ubuntu kernel has an initrd directory under /lib/modules/2.6.31-15-generic with the vesafb mod copied in. | 17:05 |
| cj | nick_schembri: seen jigdo? | 17:27 |
| nick_schembri | cj: i sorry what? | 17:28 |
| nick_schembri | cj: googling | 17:28 |
| cj | nick_schembri: oh, you're not trying to build a cdrom, eh? | 17:31 |
| nick_schembri | cj: look cool. | 17:31 |
| nick_schembri | no I run ubunt on a flash based system with aufs protecting the flash. | 17:32 |
| nick_schembri | https://help.ubuntu.com/community/aufsRootFileSystemOnUsbFlash | 17:32 |
| nick_schembri | I need to update my comments on the status of aufs in 10.4+ | 17:32 |
| cj | nick_schembri: nice. might be useful for pyramid... | 17:32 |
| cj | http://code.google.com/p/pyramidlinux/ | 17:32 |
| cj | it's based on a really old ubuntu, though, IIRC | 17:33 |
| nick_schembri | cj: i'll look at the website. | 17:34 |
| nick_schembri | cj: what i need to do is find out how long aufs will be in the kernel and build a package or ppa for the avg user. | 17:34 |
| nick_schembri | root aufs should be very simple to install and remove. | 17:35 |
| cj | nick_schembri: I dunno. I've never used aufs | 17:35 |
| nick_schembri | It's worked very well for me. I've never had any issues. | 17:36 |
| cj | you'll probably need to make-kpkg your own kernel with your own .config, though, I guess | 17:36 |
| nick_schembri | at this point the aufs modules are installed. I just need to install the userland tools and run the updates for initrd. | 17:37 |
| nick_schembri | I was hoping that linus would include aufs in the mainline kernel, but he hates the code for some reason. I'm not sure I want to maintane the patches if ubuntu pulls aufs out. | 17:40 |
| nick_schembri | cj: pyramidlinux looks a little old. I started with voyage linux out of voyage.hk. It's a debian based system that I pulled some of the code from. | 17:43 |
| cj | yeah, it's getting pretty ancient ;) | 17:44 |
| cj | but it's small | 17:44 |
| cj | I'd like to see embdebian get some love | 17:44 |
| nick_schembri | cj thanks for talking with me. I need pgraner to get back with the official answer to aufs's status in 10.4 | 17:45 |
| cj | indeed. sorry I don't know more ;) | 17:48 |
| nick_schembri | cj: embdebian would be great. I've looked a little at using debootstrap to build a sub 50M distro on ubuntu. I just have not had the time and flash memory is so cheep now I'm not sure it's worth the time. I can live with a little bloat. | 17:48 |
| nick_schembri | cj: np | 17:49 |
| cj | nick_schembri: my problem is that I've already invested in the radio hardware I intend to use, and it's only got 64 | 17:49 |
| cj | M of flash | 17:49 |
| nick_schembri | cj you should look at voyage linux it's easy to strip down. At one point it was less then 50M. | 17:50 |
| nick_schembri | Voyage Linux is Debian derived distribution that is best run on a x86 embedded platforms such as PC Engines ALIX/WRAP and Soekris 45xx/48xx board | 17:52 |
| nick_schembri | cj it looks like voyage is moving to tmpfs and it needs 128M of flash. :( | 17:54 |

| dandel | does your system crash when you suspend? (ext3 errors.) | 18:53 |
| cj | no | 18:53 |
| cj | suspend is working pretty well for me aside from sony hardware issues | 18:53 |
| dandel | strange, me and a buddy with 2 different laptops have an issue with suspend crashing. | 18:54 |
| cj | (unplugging ac sometimes kills power) | 18:54 |
| cj | dandel: did you upgrade or install karmic fresh? | 18:54 |
| * cj upgraded | 18:54 | |
| dandel | both | 18:54 |

| cj | is your friend's to an extended partition? | 18:57 |
| cj | if so, it might have something to do with extended + ext3. that's something I've never used before. | 18:57 |
| dandel | no, wubi based. | 18:58 |
